According to the Chrome team: "In bringing the Mac version of Google Chrome from its developer stages to a beta standard, we returned to the core principles of the Chromium project and focused on delivering rock-solid depth in a few critical areas for the browser, rather than a breadth of features that are rough around the edges. This first beta release for Mac does not yet incorporate extensions, bookmark sync, bookmark manager, and cookie manager. However, we focused on features such as sandboxing our renderer process to help provide a safer web experience for our users. We look forward to future releases of Google Chrome for Mac, which will fill in the gaps and provide a fast, clean browser for your enjoyment on Mac OS X."
